Patented Nov. 5, 1907.

Application filnd September 5. 1906. Serial K0. 333.307-

lwl March 13. 1906, in which thi` tank in formcd ol' thinslwct metal and enameled and ii'hich is uxwciatcd with a condensation colhrctor, also formed of sheet. mctal aml enameled and which received water of condensation tripping from thc water-coataininp,r tank.

The object of my present invention is to improve certain details ol construction of [lashing tanks of the kind specified.

My improvements are clearly chown in the awninpa'nying dmwings and will be hereinafter fully d:- ncribed.

Figure 1 shows a longitudinal vertical section through l ush tank embodying my impmvrnenta with some parts shown in l'ront elevation und sonic pans broken away to better illustmte other parts. Fig. 2 shows a front elevation of the tank on u. smaller scale. Fig. 3 shows a rear eli-mation thereof. Fig. 4 is a detail view o( the flush valve operating handle :md certain parts assmriated therewith. Fig. 5 isn similar view of n modification Figli is a detail view in perspective and onan enlarged scale of the devices employed [or operating: the ush valve. Fig. 7 is u detail view in section illumating the manner in which the tank is hcld'away from the wall to which il. is applied. Fig. 8 isn detail view of the rim oi the water-containing tank.

The general organization is similar to that Shown in my application for patent above mentioned.

The water-containing tank, A, is asmciated with a minions-ation collector, D, in this instance shown as consisting of a jacket surrounding-thc ta nk and provided with a removable cover, F.. There is nu air-space, X, between the tank and the condensation collector,which latter is pmvidrd at the rear with an opening or fenesmnn, D', to permit the free accessof air to the space, X

The tank may bc applied toawall by hangingiton suitable supports which may engage the key-hole slots, d. In order to hohl the tank away from the wall so as to 'n rmit :fir to tri-'fly circulate :mil lo mmf or pils. ont

pipe, G. In this opening is arranged o. valve-seat, M

having nn annular inclined valve-receiving portion, 1n,

from the upper edge of which. projects laterally' an annuhir flange, m', between which and the inside of the bottom of the tank is arranged a si t washer, m2. v From the lower end of the incliner] portion, m. extends downwardly a. threaded projection, M, which it will be obportion, m, and extends through an opening, a', in the bottom of the condensation collector which is 'smaller in (linmctcr than the opening. a. At its lower cnd, thc pmjecton, M', is formed with an inwardly projecting annular flange, 1n. 'lhce valveseats can he formed hy first. cutting seamless tubing into suitable lengths and then drawimrI these lengths into the required shape. By so doing, thc valve-seat may be made lighter than if made of cast metal, having the same strength and l lind there is not so much wear on the cutting tools. Furthermore, valve seats made in this way are more unit form than when cast.

The valvescat as shown in Fig. 1, projects below the bottom of the tank While the flange, m lies close to the bottom. In this way the accumulation of any considcrable amount o sediment in the tank is avoided.. T he 'here oi the valve-seat is somewhat funnel-Shaped. There is no olistruction to the free flow of flush water which will paas through the seat with great force. ln attaching.: the valve-seat. the washer, mi* is tirs! placed on it and then the projection M is passed through the opening. a, before the tank. L-is placed .within the condensation collector, then a soft washer, o, and a rnetallic washer. o, are applied.- Then a nut, O, is screwed on to the projection, M', thus clamping the valvereat to the tank, A. After this, a softwasher, o2. is applied and then the tank is placed within the condensation collector, the projection, M lieing made to pass through the opening. a. Then a soft Washer, o, and a metal washer, o, are applied and then a clamping nul.. L. is employed to clam 'i the valve-seat to the condensa tion collector. The not, O, is of such size as to act as a sparing device to hold the tank and collector a suitable dista-nce apart. The devices described therefore Prvc to firmly clamp the valve-seat to the tank and to the condensation collector and to hold the collector 'lhe flush-pipe, G, extends mln the downrard pn gestion, M of the valve-seat.

The Hush-pipe is l l 545 discharge opening, a, communicating with the flushc on'nmted with the 'gornivnailiun collector by means of 110 n brunch pipe, Q. provided with coupling devices, Q 1

und Q2. of the kind described in my application for patent before mentioned. The inlet vulve und its attachingy devices, are also similar to those heretofore employed by me and need not be here spcciliczllly described. i

The. Hush-valve, l. is in thisinstance a rubber ball and it is provided with :t stein. i, extending through u guide, l, attached to the iront `side ol' the tank. The lower end oi the 'stein screws into n ulctullicsocket picco, y, in the bull and in order to prevent this metal socket piece iront striking the guide, I/, l provide a cushion device, y. This device muy consist of a small section of rubber tubing strung on lo the stem, t3 and a rod, i, in turn connected with the valve stern, i.

i so The connecting rod, i, is formed with a loop at each end where it connects with the arm, C', and with the valve stem. This affordsV av loose connection, enabling the flush valve to be operated easily and without strain.

In order, however, to deaden or rnuflle the sound, which would be caused by the `'ibration of these parts, I apply some sound rnuilling or deadening material, 1"., i2, to the loops, preferably thelgmaterial employed is rubber. y

The valve-operating lever, C, is connected with a vert-ical rod, J, having at the top a rearwardly extending arm, j. Sound dcadening washers, J2, are arranged on the arm, j, on dpposite sides o the short arm of the lever, C, so that while the connection between the arm and the lever may be a loose one, the tendency of making a. noise by the vibration of the parts will be so reduced as to be unobjectionable. The rod, J, ex-` tends down between the front of the water-containing tank and the condensation collector. The arm, j,` at the top of the rod, J, extends across the front edge terial, j', preferably rubber, so that when the arm of the rod comes into contact with the tank, the tendency to produce a noise is avoided or reduced to such an extent ns to be unobjectionable.

At its lower end, the rod', J, is connected withthe flush-valve operating handle, K, in the manner shown in Fig. 4., This handle extends through-a slot in the front side of the condensation collector and around this slot is arranged an ornamental finishing plate, k. In Fig. 4, a washer, k, of some soft material is placed on the shank, b5, of the handle in front of the plate, k, und, a transverse pin, 1:, is applied to the shank, F, in rear of the front wall of the, condensation co1- lector to keep the handle in proper position. Sound muiliing or deadening cushions, k, El, are secured in place at the upper and lower cnds of the slot. Bythose devices, as the valve-operating handle, K, is moved up and down, it is prevented from coming directly in contact with metal and so any objectionable noise vwhich might otherwise be caused by the operation of ,the handle is prevented.

Instead of providing the devices shown in Fig. 4 l for muiiling er deadening :he sound, I may employ the i device, E, shown in Fig. 5. This consists of the flanged i sleeve applied to the shank, 1:5, which fits the slot loosely, the flange being arranged to bear on the front l of me piste, k. j The buffer, a2, shown in Fig, 2, is a device usually l employed on low down tanks against which the lid of I the seat abuts. i It will be observed that my improvements are esi pecially useful in connection with a flush tank made entirely of sheet metal. If the tank were made partly .o wood, there would not be so much necessity for dead- I ening the sound, but where the water-containing tank l is surrounded by a jacketof sheet metal and there i is an air-space between the tank and the jacket, there is a tendency to produce objectionable noises when the valve mechanism is being operated, but by my improvements such objectionable noises are eliminated. l I have heretofore found some difficulty in properly l enameling the rim of the tank. Where the rim was l iormed by turning over the upper edge of the tank and bringing the turned over portion down straightl parallel I with the sides of the tank, the enamel would not always adhere perfectly to the extreme edge of the rim. j By my present improvements, I turn the edge of the I rim inwards slightly, as indicated at z in Figs. 7 and i 8. This serves to cause the enamel to adhere while I being baked to all portions of the rim, including the extreme edge and thus imperfect enameling is entirely prevented.

In practice I ad that air pues up from the seat through the flush pipe, G, and through the branch pipe, Q, to the space between the condensation collector and the water tank and passes out through the enectrum, D. By the construction shown, air is made to freely circulate in the manner specified all around the water tank and to pass out through the fenestrum and then out through the space between the fenestrum Ler to use the buffers, d, other means may be employed ici-separating the jacket. from the wall. f 'I claim as my invention:
